ATENT OFFICE HARRY P. WALTON, OF MINERAL POINT, MISSOURI.

WEED-BURNING APPARATUS.

To all whom it may concern:

Be it known that I, HARRY I. 'WAn'roN, a citizen. of the United Statesof America, re siding at Mineral Point, in the county of 5 Washingtonand State of Missouri, have in, vented certain new and usefulImprovements in Weed-Burning Apparatus, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to an apparatus for burning weeds, and has for itsobject the production of an apparatus of this description that may bepropelled by manual or other power, and by which weeds in the path inwhich the apparatus is moved may be effectively burned to the ground.

Figure I is a top or plan view of my apparatus. Fig. II is a sideelevation of the apparatus. Fig. III is an enlarged cross section at thelocation of the burner. Fig. IV is in part a rear elevation and in parta longitudinal section through the burner and the parts adjacentthereto. Fig. V is a section taken on line V-V, Fig. III.

In the accompanying drawings: 1 designates the side bars, and 2 a crosspiece or platform, which combinedly constitute the main frame of myapparatus. The frame just mentioned is supported by an axle 3 and groundwheels 1 fixed to said axle. At

one end of the axle 3 is a crank arm 5.

6 designates handles connected to the side 'These handles are pivotallconnected to the frame side bars at 7. 11 order that the main frame maybe maintained in a horizontal position while the apparatus is in use, orin an inclined position relative to a horizontal plane, I provide meanswhereby the handles may be held in fixed positions when they arearranged leither in alinement with the main frame or at an anglerelative thereto, such means comprising socket members 8 fixed to thehandles and straddling the rear ends of the frame side bars, the socketsbeing provided with segmental slots 9; and I mount in the sidebars neartheir rear ends bolts 10 provided with clamping nuts 11, through themedium of which the socket members may be held from movement when thehandles 6 have been adjusted to positions in alinement with, or out ofal'inement with,

the side bars of the main frame.

upon the cross piece 2 of the main frame of my apparatus, and which isadapted to contain a supply of gasolene, or other liquid fuel. Toprovide for the delivery of the fuel from this tank to the burner to behereinafter described, I furnish in the apparatus 'a pump barrel 13 thatis connected to the fuel tank by a pipe 14. \Vithin the pump barrel is apiston 15' that is operable by a piston rod 16 connected to the crankarm fixed to the axle 3. The connecting pipe 14 contains a union 14:that permits swinging movement of the pump barrel 13. During therotation of the axle 3 and the crank arm 5, the piston rod 16 isreoiprocated to move the piston in the pump barrel, during which action,the pump barrel partakes of a swinging movement that is renderednecessary due to the movement of the crank arm 5 in a circular path byreason of said crank arm -post, will act to hold the housing in anyposition to which it may be adjusted. The

housing 18 extends transversely of the main frame of my apparatus and isof an inverted trough shape, 'the ends of the housing being closed byend plates 21 (see Fig. 1V). Within. the housing are inclined. divisionplates 22 that serve :to subdivide theinterior of the housing intochambers 23 that are narrow at their upper ends and widen graduallytoward their lower ends. Air is admitted into these chambers from theexterior of the housing due to the provision of air inlet openings 24 inthe side walls of the housing.

25 is a spreader, of inverted V-shape in cross section, that extendslongitudinally in the housing 18. This spreader is located immediatelybeneath the burner in the housing 18 and also serves as a superheaterfor the gas in said burner, thereby increasing the efficiency of actionof the burner.

26 designates a burner pipe located within the housing 18 near its topand extending longitudinally of the housing above the spreader 25 (seeFigs. III and IV). This burner pipe has arranged therein a plurality ofburners 27 havingnutlet ducts 28 that are controlled by valve rods29,7preferably terpminating in needle valves. that enter into the ducts28. Fuel is delivered to the burner pipe 26 to be,discharged therefromthrough the burners 27 through a 'fiexible conducting pipe-30leadingfrom the fuel tank- 12 to the burner pipe.

31 designates a roller arranged in front of the burner housing 18 andsupported by said housing through the medium of arms 32 fixed to thehousing. This roller is designed to depress weeds that may beencountered thereby during the operation of my weed burning apparatus,so that such weeds may be lowered to the ground to be readily passedover by the burner housing,- in order that a flame directed downwardlytherein from the burners may effectually destroy. the

weeds by burning them as the housing passes thereover.

33 designates shields located at the ends of the burner incasing housing18 and which preferably comprise plates with insulating material betweenthem, as seen in Figs. IV and V. Ihese shields are employed to pre ventthe spreading of flames ejected from the burner incasing housingvtopoints beyond the ends of the housing, so that the burning of the weedswill.be confined to a given course corresponding in width to the widthof said housing. The shields are connected to the housing at its ends byhinges, the

hinge at the end of the housing supported by the post 17 being locatedat the front of the housing, while the hinge at the opposite end islocated at the rear ofthe housing,- as seen in Fig. I. The hinges just-n1entione'd comprise leaves 34 attached to the housing and providedwith ears 35; leaves 36 attached to the shields and each provided with"an car 37 and pivot pins 38 immovably mounted in the ears 35 of thehinge leaves 34, see Figs. III and V. Theears 37 of the hinge leaves 36receive set screws 39 that are adapted to bear against the pivot pins 38for the purpose of holding the shields 33 from movement after they havebeen ad-- justed relative to the ends of the burner incasing housing 18.

In'the practical useof my weed burning apparatus, the burner housing andappurtenances associated-therewith may be readily adjusted relative tothe main frame by moving the bracket 19 upwardly or downwardly I uponthe post l7,lin order that these parts eeaiai the housing, as seen indotted lines, and held in such positions under the ends of the setscrews 39.

While I have described my PP as intended for use in burning weeds, Iwish it understood that I do not limit myself to the use of theapparatus for this particular purpose, inasmuch as it may besuccessfully employed for other purposes, such as'for instance, themelting of ice upon roadways or pavements in winter.

I claim:

1. In an apparatus of the character described, a main frame, a burnerhousing carried by said frame, laterally movable shields hinged to saidhousing at its ends, the hinge at one end being located at the front ofthe housing and at the other end at the back of the housing, and aburner in" said housing.
